Hollow carcass for filling cast-in-situ concrete

Abstract

Disclosed is a hollow matrix for filling cast-in-situ concrete, which comprises a hollow matrix (1), wherein an outer wall (3) is enclosed to form the hollow matrix (1) having a cavity (4). The hollow matrix is characterized in that at least one outer wall board of the hollow matrix (1) is formed by warping a prefabricated outer wall slab (6) on the slurry blank (5) of the outer wall (3), the hollow matrix (1) having an opening on one side is fabricated, the prefabricated outer wall slab (6) is hanged or put on the opening surface, and the prefabricated outer wall slab (6) is sealed by the slurry blank (5). In this way, the hollow matrix has easy manufacture, high production efficiency, and lower cost; meanwhile, the hollow matrix also has the characteristics of simple structure, high intensity, large rigidity, excellent anti-deformation and vibration resistance performance, convenient construction, fast construction speed, and the like, and is adapted to hollow slab, floor, roof, wall, base plate and bridge made by cast-in-situ reinforced concrete or prestressed reinforced concrete, especially suitable for hollow girderless floor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 11, 2004, an application number of 200410155211.9, and a title of "a hollow matrix for filling cast-in-place concrete". (1) Technical field [0002] The invention relates to a hollow matrix for filling cast-in-place concrete. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a p...

Problems solved by technology

But when this kind of hollow carcass is applied to the floor construction, the hollow carcass cannot be accurately arranged in the middle layer of the floor, which affects the construction quality of the floor

For this reason, the patent No. is ZL01215092.4, and the name is "building component" utility model patent. The disclosed building component is a polyhedron, which can be hollow or solid. In order to ensure that this building component is applied to the floor It is arranged in the middle layer of the floor, and the outer wall of the polyhedron is provided with protruding legs, so that when the floor is poured, the legs can ensure that the hollow multi-faceted main cavity is just at the middle layer of the floor. , so as to better solve the above problems, but the production of this kind of building components is inconvenient, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high
